Chiral and steric recognitions play critical roles in selective binding and resultant high stereo- and enantioselectivity in chemical reactions mediated by bioactive macromolecules such as enzymes and nucleic acids. Herein, we report the presence of both strong chiral and steric recognitions between optically active, highly isotactic, alternating {alpha}-olefin-carbon monoxide copolymers with 1,4-keto groups in the backbone and their effect on both the physical properties and chemical reactivity of the polymers. Thus, an alternating {alpha}-olefin-carbon monoxide copolymer with a given chiral sense for the tertiary carbons in the main chain can distinguish (a) between the two possible chiral senses for the tertiary carbons in the main chain of a second {alpha}-olefin-carbon monoxide copolymer even when the latter has a different pendant alkyl group and (b) between the length of the pendant alkyl group in two different copolymers whose tertiary carbons have the same chiral sense. 7 refs., 3 figs., 2 tabs.
